New Delhi: A 69-year-old woman Carolyn Hartz, from Perth, Australia, looks nothing like her age.

It is amazing to see how a grandmother of four has managed to maintain a healthy lifestyle for so many years.

According to a report in Thehealthsite.com, Hartz was diagnosed with pre-diabetic when she was 40 years old. She loved sugar and was once addicted to sweets. But when she was diagnosed with pre-diabetes, she gave up sweet products in her life to get back the sugar levels on track.

Since then, she started using a sweetener called Xylitol, a sugar substitute which is completely natural.

The 69-year-old woman revealed that a sugar-free diet, exercise and proper sleep are the reason behind her youthfulness.

She said that eating protein during meals, especially breakfast, does wonders for her body as it curbs the cravings.

She will turn 70 next month and was the one to introduce Xylitol to Australia.

Carolyn Hartz story has proved that a healthy lifestyle should be everyone's number one priority.
